I wonder if it would be possible to have a debate site that didn't degenerate into noise? How would you keep things civil? Or how would you keep it from becoming an echo chamber?
One of my most frequently made comments in discussions about United States politics is that Americans need to learn more about public policy in other countries. (I am an American who has lived overseas for years at a time.) So I would perpetually be stretching the boundary of "US" politics if I participated on such a forum.
